I am finally through dealing with Coralvue!!!! They don't want to do anything about the noise issue with my skimmer! They have referred me back to the retailer, which is Reef Specialty, and I'm not going to bug Mike or Jeremy about a problem that is not theirs, but Coralvue's. When I inquired about Coralvue purchasing my skimmer back from me or exchanging it for another model not using the sicce pumps, I was quoted a price on a different skimmer and told to try and sell my skimmer for as much as I could get for it. Yeah right.....like I'm going to stick it to someone with a skimmer that's loud as a food processor or garbage disposal. I am done trying to work with Coralvue on this issue and since my skimmer is still WELL under warranty I will start to pursue other actions to get this problem resolved. I will never pay my hard earned money to a company that won't stand behind it's products or won't honor it's warranty. BUYERS BEWARE OF COMPANIES LIKE THIS!!!!!!!
